-check_ldap_repl - nagios/icinga plugin to check correctly working of ldap replication.
+check_ldap_repl - nagios/icinga plugin to check ldap replication. This works by
+updating an entry on the provider and checking whether the update is replicated
+by querying the consumers for the updated entry after a short waiting period.
